Background: This study aims to assess the relationships between sphenoid sinus (SS) types, septation, lobulation, symmetry, septal deviation, and the variations in SS pneumatization regarding the surrounding neurovascular structures using Computed tomography (CT) images. Sexes and age groups were investigated.
Material And Methods: We retrospectively evaluated head CT-scans of 320 patients (age range 18-49 years); mean of 43.
SARS-CoV-2 variants are mainly defined by mutations in their spike. It is therefore critical to understand how the evolutionary trajectories of spike affect virus phenotypes. So far, it has been challenging to comprehensively compare the many spikes that emerged during the pandemic in a single experimental platform.

This systematic review aggregated and analyzed data from literature on sex differences in neurocranial dimensions as measured by computed tomography (CT). Following registration of the review protocol with PROSPERO (#CRD 42023442451), comprehensive searches were conducted in six databases and gray literature.

- This study aimed to identify respiratory clinical signs and thoracic radiographic abnormalities in dogs with hypercortisolism, a condition caused by excess cortisol.
- The researchers found that common symptoms included snoring, coughing, and fatigue, alongside significant findings on lung auscultation.
- Radiographic changes were present in 47.5% of dogs, particularly bronchial patterns, indicating that respiratory issues and obesity are frequent in these affected dogs.
Article Synopsis
- Trypanosoma vivax infections are prevalent in Africa and were introduced to Latin America in 1919, causing trypanosomosis, with some local cattle breeds (trypanotolerant) showing resilience against the disease.
- A study evaluated the Curraleiro Pé-Duro (CPD) breed's ability to meet trypanotolerant criteria compared to Holstein/Gyr breeds by assessing their response to T. vivax infection over 532 days.
- Results indicated that CPD animals maintained normal health without treatment and demonstrated recovery from anemia, while the Holstein/Gyr breed exhibited significant weight loss and required treatment after infection.
